For some reasion I seem to be getting through alot of oil, iv had the car up in the air and it's bone dry underneath, I never had any oil patches on the floor, I don't get any smoke on idle or boost and the engine was rebuilt jan last year. I only really use the car on weekends but iv used over 5L in the last 3 months ( I know that dont sound too bad but iv had the car 6 months and put less then 1000 miles on it)

Any sergestions or help on this would be great
